feat(tests): add comprehensive test infrastructure based on blockchain pallet tests

Created complete testing framework for web and mobile frontends based on 437 test scenarios extracted from 12 blockchain pallet test files.

Test Infrastructure:
- Mock data generators for all 12 pallets (Identity, Perwerde, Rewards, Treasury, etc.)
- Test helper utilities (async, blockchain mocks, validation, custom matchers)
- Example unit tests for web (KYC Application) and mobile (Education Course List)
- Example E2E tests using Cypress (web) and Detox (mobile)
- Executable test runner scripts with colored output
- Comprehensive documentation with all 437 test scenarios

Coverage:
- pallet-identity-kyc: 39 test scenarios
- pallet-perwerde: 30 test scenarios
- pallet-pez-rewards: 44 test scenarios
- pallet-pez-treasury: 58 test scenarios
- pallet-presale: 24 test scenarios
- pallet-referral: 17 test scenarios
- pallet-staking-score: 23 test scenarios
- pallet-tiki: 66 test scenarios
- pallet-token-wrapper: 18 test scenarios
- pallet-trust: 26 test scenarios
- pallet-validator-pool: 27 test scenarios
- pallet-welati: 65 test scenarios

Files created:
- tests/utils/mockDataGenerators.ts (550+ lines)
- tests/utils/testHelpers.ts (400+ lines)
- tests/web/unit/citizenship/KYCApplication.test.tsx
- tests/mobile/unit/education/CourseList.test.tsx
- tests/web/e2e/cypress/citizenship-kyc.cy.ts
- tests/mobile/e2e/detox/education-flow.e2e.ts
- tests/run-web-tests.sh (executable)
- tests/run-mobile-tests.sh (executable)
- tests/README.md (800+ lines of documentation)
